I need to know a couple things.
What is the terminology for the pop-up box shown in this Image? (Not the text, but the actual box itself) This is with Visual Studios.

I need to do a project in Java and I heard that Eclipse has this pop-up box, but I cant seem to find it. Does anyone know where this option is? I was hoping maybe finding out the terminology of the box will help me find the option easier.
Is there a better IDE for java than Eclipse with this box included?
Thank you for the help.
This is IntelliSense, it's activated automatically, but can be invoked manually using Ctrl+Space.
Yes, Eclipse does have this as well. Press Ctrl+Space to bring it up (I don't think Eclipse does it manually - it's been a couple of months since I last used Eclispe so I may be wrong).
You might want to look into IntelliJ IDEA or Netbeans (the former over the latter). IMHO, Eclipse is the most powerful and represents best value for money :-)

I've recently moved from Eclipse to Intellij IDEA for java development,
I have some code as shown in the screenshot, and as you can see there is no package called test2, Eclipse used to give suggestion if I want to create/move such a package, what is the IDEA equivalent shortcut for that option ?
Context specific actions can be brought up by alt+enter while having your cursor on the underlined part.
May I also suggest ctrl+shift+a. This brings up a search field for all kinds of menu items and settings.
Edit
Two more tips I always give IntelliJ newcomers:
Regularily check out Help/Productivity Guide. It tells you which features you don't use yet.
Install the Key promoter plugin. It tells you which shortcuts you could have used when you use an IntelliJ-Feature.
I know the question is very long, but in a nutshell it's just that. As you know Netbeans has a feature with the help of inno setup that allows the creation of .exe installers of Java applications. The problem is that I would like to change the default icon it has (a grey java icon) for a custom one.
I have searched a lot through both Stack and Google and I haven't found anything. The closest it got is to change it via Launch4j. The thing is if it is possible to do it within Netbeans.
Furthermore, I was wondering if there is a possibility to add several languages to the installer and some other features like the creation of a desktop icon. I guess if the option exists it would be in the same place as the change-icon... but I am completely lost regarding this issue.
I have been wracking my brain trying to figure this out. For the first time I used jEdit the other day and I was pleasantly surprised that it auto indented my code (meaning that I'd put in the following code:
int method () {
_ //<-- and it put me here automatically
I've tried to get the same thing working with eclipse but with no success. I got into the code formatter but I don't see how to make that happen.
Is it possible to do this? Also while I'm here, is there a such thing as a eclipse plugin that will allow you to search the methods and classes of the standard java library?
Thanks
Personally all I use for this is the format options Window->preferences under Java->Code Style ->Formatter.
I once took the time to tweek how I like my code to look like when I work and exported the whole thing. After that I just code without too much bother on what it looks like. When I find the code looks messy by pressing the combination ctrl+shift+f and the whole class becomes pretty again, comments and all.
After a while it pretty much became a reflex...
code code code
ctrl-s, ctrl-b (cause I disable auto build sometimes), ctrl-shift-f
code some more etc...
Once I got used to this I never really cared how it presented the code as i was typing because I knew it would look all pretty as soon as the loop/if/switch/method etc is finished
My clean eclipse install does this by default.
Have you changed any options? Make sure the file you are editing has the .java file extension. The preference options that control the typing automations are under Java -> Editor -> Typing in the Window -> Preferences menu.
Also, I find that the auto-indenting, and most of the other auto-complete functions of eclipse do not function well if the file I am editing has errors in it which prevent compilation. Make sure that your curly-braces are matched correctly, this is the main one that I've noticed blocks auto-indent.
Regarding searching through the standard Java libraries, use the Search -> Java.. menu option, and check the JRE libraries checkbox, then search away. You can also use the Hierarchy view to see how the classes relate. Also, in the Package and Project views you can expand the JRE System Library, and then expand rt.jar which holds pretty much all the standard Java pacakges.
Eclipse has always done this for me by default.
One really cool thing about eclipse is that you can search preference pages. Just right click and go to prefrences. Go to the "Window" menu, and click "Prefrences". Then at the top of the tree view there's a text box that says "type filter text". Replace that with "indent" and it should bring up the page where the indent option is.
Make sure that eclipse recognizes your file as a java file, that you're using the Java distribution, the latest version, etc.
Iv been trying to work around the eclipse indenting and other supposed features for years, and it seems that the bottom line is this ...
It only works for the programming style of the authors, so to use it you need to modify your style to comply.
This would be OK except that the authors of eclipse have some very strange ideas about common shortcut keys.
One horrid example is the search features, eg when did Ctrl+K become "Find Next occurrence" and why doesnt F3 or n work?
That all being said I use eclipse because if you have the time to wait around while it starts up - or never close it - and you can modify everything youve learned about using an editor - why why why - then it will certainly increase your efficiency.
Please note that there is a preference setting for indenting, it can be set for a project, a workspace, or globally, but no matter how you set it eclipse will still chuck tab characters in where you dont want them.
In fact its indent crazy, like it wants to indent everything, even if its already indented.
Like I said Iv been using it for years and it STILL drives me nuts with its random behavior.
Follow these steps for Eclipse:
Select all text: ctrl+A
Correct indentation: ctrl+I

What is your favorite hot-key in Eclipse?
I just started using eclipse for some personal projects and am finding the transition from IntelliJ (what I use at work) kind of annoying. I hope it's kosher to ask a few different questions in the same thread. Here goes:
1) How do I get "views" (I'm not sure if this is the term. I mean windows such as Project Explorer, Servers, Console, etc) to stay expanded and on top even after I've clicked back on the editor or another view. I'm pretty sure that right now all of these tabs are "quick views" that I have minimized and then docked, so I may not be doing this right to begin with. In IntelliJ, I would simply just pin the tab.
2) How can I open a file (for instance, an ant build.xml) without having to make it part of an eclipse project? I want the syntax highlighting and Ctrl-click ability that the IDE will give me (not to mention being able to use eclipse's built-in ant), but I don't need to associate the file with any others and so don't see the point of having to make it a part of a project.
3) Is it just me (wouldn't be surprised) or does eclipse have a bug with parsing empty html tags within the body of html tags of the same type. I've only tested this in a JSP, and it doesn't happen with JSF tags. For example: <div id="foo"><div id="bar"/></div>. Eclipse will give a warning saying the first div tag has no end tag. This is with the most recent version of eclipse for Java EE, no plugins have been installed.
4) Finally, a general question: Any best practices or resources to look at for organizing the eclipse interface and perspectives/views? What about workspaces/projects? Is there some tutorial out there that would be really informative that I could read through in less than an hour?
I appreciate any answers and tips/tricks.
First of all, please acknowledge that there are different people in the world and there are people who don't work the "Eclipse way". Even if I was paid for it (and I am), I couldn't work with IDEA. So if Eclipse rubs you the wrong way, it may not be for you. That out of the way, your answers:
In Eclipse, you open a view and let it stay where it is. In IDEA, the view changes all the time, things pop up and go away. Eclipse is static unless you specifically move things around. There are two ways to move things: You can minimize a part (a part is something which contains tabbed views). This moves the part into the closest border. Or you can maximize the current part (Ctrl-M). This pushes all other parts out of the way. Another Ctrl-M will restore the view.
This is a good place to show the difference between IDEA and Eclipse. IDEA tries to anticipate what you're doing and to be helpful. For me, this means it always gets in my way. It will start to format source as I type, things move, etc. That freaks me out. Eclipse is like a toolbox. Everything is there but you have to pick it up. A toolbox doesn't move on its own accord and it doesn't try to be smart.
Eclipse is based on the idea of a workspace. The workspace is the universe and nothing outside exists. If you need to go outside, you must first create a file or folder. In the "New File/Folder" wizard, you can open the advanced options (at the bottom) and link this resource to a real file/folder in the file system. May sound like a lot of effort but it allows Eclipse to display virtually anything in the explorer since it just shows "resources" in there, not actually files.
Smells like a bug. Please report it at https://bugs.eclipse.org/bugs/
I'm not aware of anything.
[EDIT] 3. As cletus pointed out, is not valid HTML. So that might cause the warning.
An Eclipse Perspective is a collection Views and their position. You can customize or create new perspectives, but the existing ones are good enough for a start (Java, J2EE, Java Browsing etc.). I recommend to stick with the default layout for a while until you've managed to use the quick view feature (which, personally, i find quite annoying). On small screens, i simply like to use Ctrl-M to switch the Editor to fullscreen mode and back, without the need of minimizing single views or move them around.
Yes, you can run external build scripts as well and it's called External Tool in Eclipse. Go to Run > External Tools > External Tools Configurations. Create either a new Ant-based config or a native executable (Program). The location of the build script or executable can either be workspace-relative (Browse Workspace) or absolute on the file system (Browse File System)
I'm looking at learning JavaFX.
I've tried setting Eclipse to develop a small app and I've downloaded the Eclipse plugin.
Eclipse JavaFX plugin
BUT... it just seems, well, flakey.
So I have 3 questions...
1: Is there a better plugin?
2: Or is there some great set of tutorials out there that I'm missing?
3: finally, is it meant to be easy to call Java code from FX? I'm stuggling, it there a good example somewhere?
On questions 1 & 2, Eclipse underlines code in red that just shouln't be. For example..
see this image... alt text http://www.qenet.co.uk/fx.jpg
Why does it underline bit of imports in red?
I know this is little of an open ended question. So I guess my main question is this...
Is my experiance of JavaFX and Eclipse the best I can hope for? Or am I missing something ?
(and I'm not looking for a Yes/No response) :-)
Just looking for a discussion on how best to learn/develop JavaFx.
This kind of thing is not unusual. A lot of Eclipse plugin editors have problems dealing with error tags and the like. For example,
I find that the XML and HTML file editors often fail to clear error and warning markers, and the only way to get rid of the markers it is close and reopen the file.
Even the Java viewer gets it wrong in some circumstances, though the problem goes away when the relevant files are saved.
When you update a spelling dictionary, the spelling checker is not rerun and the spelling error markers are not updated. In fact, you have to restart Eclipse for this to happen.
I suggest that you try saving files, and closing/reopening editors to see if that makes the bogus error markers go away. Then decide whether Eclipse is the right IDE for this task.
I've never used NetBeans (at all), but you would expect that it would do a better job supporting JavaFX. After all NetBeans and JavaFX are both high profile Sun products at the moment.
Netbeans is really the only way to go at the moment for JavaFX development. They are both Sun products and Sun has made sure the two work very well together. Before long Eclipse and others will catch up but for the moment that's how it is.
There is another JavaFX plug-in for Eclipse from Exadel. You can download it here: http://exadel.org/javafxplugin. Give it a try.
I have similar problems but funnily only under Linux, not Windows. Hope they change that soon.
To me this has happened when I wronlgy installed javafx sdk 1.2.3....This plugin works only with 1.2.1... :/
